Perpendicular. If a current carrying wire is placed in a magnetic field perpendicular to the wire it experiences a maximum force

<u>Answer:</u> The force will be maximum when the current is moving at an angle of 90°

<u>Explanation:</u>

The relationship between the force on a current carrying wire and magnetic field is given by the formula:

\overrightarrow{F}=\overrightarrow{I}L\times \overrightarrow{B}\\\\\overrightarrow{F}=ILB\sin \theta

where,

I = current flowing through wire

B = magnetic field

L = length of the wire

F = force on a current-carrying wire

The value of \sin \theta is maximum for 90°, which is 1.

Hence, the force will be maximum when the current is moving at an angle of 90°

Nostrana [21]

Answer:

a. 1100 meters.

b. Between B and C

c.1. Between point D and E

c2. Between point D and E

d. 3.7 m/s.

Explanation:

The girl travels the distance of 1100 meters from starting to the end. There is no motion occurs between B and C due to no change of distance value from 200 meters. Between point D and E, the girls covers 500 meters long distance and also covers fastest distance between point D and E because between point D and E, the girl covers 500 meters distance in 30 seconds which is the highest of all. The average speed of the girls is 3.7 meter/seconds if we divide total distance i.e. 1100 meters by time which is 300 seconds.

A set of data is collected for object in an inelastic collision, as recorded in the table.
TiliK225 [7]

Answer:

To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.

Object 1 has momentum of 8 kg. m/s before collision.

Object 1 has momentum of 0 kg. m/s before collision.

The combined mass after the collision had a total momentum of 8 kg. m/s.

Explanation:

Momentum of the object is given by,

Momentum = mass × velocity

For object 1:

Momentum = mass × velocity

Momentum = 2 × 4

Momentum = 8 kg. m/s

For object 2:

Momentum = mass × velocity

Momentum = 6 × 0

Momentum = 0 kg. m/s

For object 1 + object 2:

Momentum = mass × velocity

Momentum = 8 × 1

Momentum = 8 kg. m/s

To identify the momentum of object 1, you must multiply mass (m) and velocity(v) to find momentum.

Object 1 has momentum of 8 kg. m/s before collision.

Object 1 has momentum of 0 kg. m/s before collision.

The combined mass after the collision had a total momentum of 8 kg. m/s.

How many newtons of force
Alisiya [41]

The amount of force needed by the truck to move the boulder is 200 N.

<h3>Force:</h3>

This can be defined as the product of mass and acceleration. The S.I unit of force is Newton or kgm/s²

To calculate the newton's of force a block needs to move, we use the formula below.

Formula:

  • W = Fd............. Equation 1

Where:

  • W = Work done by the truck
  • F = Force applied on the boulder
  • d = Distance moved by the boulder

Make F the subject of the equation

  • F = W/d................. Equation 2

From the question,

Given:

  • W = 2400 J
  • d = 12 meters

Substitute these values into equation 2

  • F = 2400/12
  • F = 200 N

Hence, the amount of force needed by the truck to move the boulder is 200 N.
